End-tooth combine, piston 2 push driving gear disc 6 to diagram right direction move, make driving gear disc 6 and driven 11 end face of fluted disc
Tooth combines, and driven end transmitting one-way moment synchronous with drive end is on the contrary then do not transmit；
Unidirectional device 12: due to internal structure design, unidirectional device 12 only unidirectionally can be such that inner ring turns simultaneously with outer ring
Dynamic, reversed inner ring and outer ring rotating separation cannot rotate simultaneously；
Bearing B13: inner hole is coupled with equipment output shaft, and outer ring is coupled with support base 7, plays support support base
7 effect；
Circlip B14: axial limiting is carried out to bearing B13；
Sealing ring A15: being installed on equipment transmission shaft and 1 pressure source entrance of cylinder seat, seals to entrance, pressure is prevented to be situated between
Matter leakage, causes stress loss；
Sealing ring B16, sealing ring C17: being coupled with cylinder seat 1, piston 2, guarantees that pressure medium does not leak, cylinder internal pressure
Power is stablized；
Interstage sleeve 18, retaining ring 19: being mounted on equipment transmission shaft, after guaranteeing that one-way clutch integral installation is good, axially continuously
Gap, without play phenomenon when operation.
Structural principle: as shown in Fig. 2, this one-way clutch design be based on unidirectional device 12 can only unidirectional delivery torque this
One feature increases mechanical mechanism in 12 periphery of unidirectional device, makes one-way clutch at work, in addition to unidirectional delivery torque,
It is able to achieve the function of clutch on-off.
This structure clutch working principle: to pressure source import 20, it is passed through pressure medium, such as compressed air and pressure oil),
Push piston 2 to the movement of diagram right side, so that driving gear disc 6 be driven to move the end-tooth knot up to driven fluted disc 11 to the right
It closes, i.e., one-way clutch combines, so that the drive end and equipment output shaft that connect at ring flange 3 be made to can be realized based on unidirectional dress
12 unidirectional delivery torque is set, other direction cannot transmit torque, and when pressure source pressure release, reset spring 8 pushes driving gear disc 6
To the movement of diagram left side, until driving gear disc 6 is separated with the end-tooth of driven fluted disc 11, realize that one-way clutch disconnects, arbitrarily
Direction cannot transmit torque.
This programme: by being passed through pressure source (such as compressed air, pressure oil) into clutch, combining clutch, from
Clutch unidirectional delivery torque, torque is not transmitted in reversed idle running, and when pressure source disconnects, clutch is resetted by reset spring 8,
Clutch disconnects, forward and reverse freely to dally, and does not transmit torque.
Protection requires:
1. not using end-tooth, combined using friction-type part, realizes the one-way clutch of clutch combination, break function
Device；
2. not using pressure medium, the one-way clutch of clutch combination, break function is realized using electric or hand function
Device；
3. not entering pressure medium from equipment output shaft, clutch combination is realized from cylinder seat axially into pressure medium, is broken
The one-way clutch opened.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
